Multiple SDKs conflict

Lailla

I have build the Qt source on Windows 10 using Admin x64 Native Tools Command Prompt for VS 2019 and the command:

configure.bat -debug-and-release -platform win32-msvc -opensource -confirm-license -force-debug-info -webengine-proprietary-codecs -feature-vulkan -no-schannel -openssl-linked -prefix "C:\Qt\6.6.0" -- -D OPENSSL_ROOT_DIR="C:\Program Files\OpenSSL"

After the compilation have finished configure.bat > cmake --build . --parallel > cmake --install .

I had compiled the source many months ago until today I had not modified anything else in the sources or in any file on C:\Qt\6.6.0.
I did a small modification on qtextdocumentlayout.cpp i had just changed:
idealWidth += marginWidth.toReal();
to
idealWidth += marginWidth.toReal() + 10;

and then i open Admin x64 Native Tools Command Prompt for VS 2019 again cd C:\Qt\6.6.0 and called ninja.

It started compiling the modifications and stopped with this error:

C:\Qt\6.6.0>ninja

C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\ucrt\corecrt.h(263): error C2953: '_CrtEnableIf<true,_Ty>': class template has already been defined
C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\ucrt\corecrt.h(260): note: see declaration of '_CrtEnableIf<true,_Ty>'

Why is it trying to use two different sdks?

10.0.26100.0\ucrt\corecrt.h(263):
10.0.22621.0\ucrt\corecrt.h(260)

As i mentioned i did not modified anything else than qtextdocumentlayout.cpp and then i called ninja.

Even reverting the modification i continue getting the same compile error.

I tried to attach my CMakeCache.txt file but i wasn't allowed to upload files, i have upload it here.

Why is this error happening?
